Below is a summary of potential PlayStation 4 features and specs based on the PS4 concept renders from Joseph Dumary, as follows:

PS4 Concept Render Features:

PS4 will be part of the PlayEco line which uses 0 watts in standby.

ECO Restart function allows the player to save their game and turn off the console, turn it on and resume the game without loading where they left off.

PS4 will automatically shut off primary power after each 30 minute period of playtime and draw energy from a rechargeable battery for 5 minutes.

Playr (PlayReserve) rechargeable battery also assists in preventing data loss during a power outage.

PS4 offers retro appeal - looks like a mix between a PlayStation 2 Slim and a Memory Card.

PlayStation 4 will be made of 60% recycled material, a magnesium alloy and carbon (25%).

PS4 is light and efficient, weighs only 2.1 KG, and consumes only 90 watts.

PS4 will be compatible with PS Vita, allowing players to use it as a remote control for browsing the Internet or play some games using the touch capabilities.

PlayStation 4 will also be compatible with Sony tabs and all Sony devices with multitasking capability allowing users to pause a game, go to PlayStation Community Gaming, watch videos on the YouTube application and resume the game.

PlayStation Community Gaming will be a portal dedicated to gamers, where you can chat (text or video) with other players, share your games, walkthroughs, or connect with players having the same game with the search function.

TVs will be automatically detected and selected according to the resolution of the screen by default - all in less than 4ms.

DPConnect Advanced allows for two (or six) players on two (or six) different TVs with the same console, so everyone can see his game without splitscreen. The distance between the console and the TV should be 7.5m maximum.

PS4 controller has a light sensor (for screen luminosity), an option screen to adjust settings such as the rigidity of the analog sticks (the stick will be difficult to maneuver in some parts of certain games for total immersion), and the battery level.

PS4 screen allows players to access options including battery management and some option adjustments of the PS4 console without pausing.

PS4 Controls charge via USB or inductive charging.

PS4 includes a one-touch power button, and all options appear.
